SHINGLE.

Application filed July 13, 1925.

This invention relates to shingles and particularly those which are composed of flexible composite sheets. One of the objects of the invention is to provide means for locking down the exposed lap portions of the shingles so as to prevent these portions from warping or being blown upwardly and thus causing a tendency to leak and also affecting undesirably the appearance of the roof.

Another object of the invention is to provide shingles shaped so as to expedite the laying of the shingles on the roof. Another object of the invention is to present a pleasing appearance for the roof. And another 1; object is to provide means for decreasing the tendency of the shingles to leak.

Of the accompanying drawings Fig. 1 is a plan view of a plurality of shingles as they appear when assembled, and which embody the features of my invention; Fig. 2 is a plan view of an individual shingle; Flg. 3 is an enlarged sectional view along the line 33 of Fig. 2; Fig. 4. is a plan view of a plurality of modified shingles as they ap pear when assembled; Fig. 5 is a plan view of an individual modified shingle; Fig. 6 is an enlarged sectional view along the line 66 of Fig. 5; and Fig. 7 illustrates a modified way of assembling shingles such as those illustrated in Figs. 4 to6.

In forming roof coverings with shingles it is desirable to provide a pleasing appearance for the roof, and, to accomplish this, consideration must be given to the appearance of the shingles after they are laid rather than to the appearance of the indi-' vidual shingles. Also the shingles should be made and laid so as to maintain this pleasing appearance in spite of the effects of the weather. While the general shape 0 the shingles which I have invented may be modified more or less without de arting from the spirit of my invention, yet prefer shingles t at will produce when laid substantially a square or diamond-shaped figure. I also provide shingles which may be inclined more or less having either the corners or the edges extending longitudinally and transversly of the roof.

The shingles 10 of Fig.1 are laid with one corner 11 extendin downwardly, and the exposed or lap portions 12 of the shingles are locked down by slip ing the corner 11, or a portion thereof, un er a portion 0 the adjacent underlying shingle in the same row. To assist in this I provide on two ad- Serial No. 43,188.

j acent corners of the shingles tongues 13 and 14 and slots or slits 15 and 16. And on the other two adjacent corners I provide slits 17 and 18. The shingles so formed are laid as indicated with the tongues 13 slipped under the. corners 21 of the adjacent underlying shingles in the same row, and with the slits 15 and 17 interlocking, so that both of the corners 11 and 20 are thus held down by the adjacent shingles.

At the same time the tongues 14 are slipped under the corners 21 of the underlying shingles of the same row, the slots 16 and 18 of the respective shingles interlocking. So that the shingles in each row are locked together on both sides forming substantially a continuous strip of shingles. When so formed the exposed portion of any one shingle can not warp upwardly as it is held down by the adjacent underlying and overlying shingles. And when so connected the different rows may be lapped as much as may be desired. For instance, as indicated, the overlying rows la on the adjacent rows substantially one fi th of the way; and, to facilitate laying of the shingles, notches 22 are formed therein corresponding to the projections 23 on the opposite edges. And the overlying rows of shingles may be lapped upon the adjacent rows until the edges register with the projections 23 of the underlying shingles. Obviously the lap can be as much as desired and the projections 22, ifproperly placed, will form guides for the proper lapping of the shingles.

Also when the shingles in the respective rows are thus connected the rows may be in clined as much as may be desired by laying the first row with the desired inclination f and the others will assume the same inclination. So that the inclination may be as indicated in Fig. 1 or as indicated in Fig. 4 or any intermediate inclination which may be desired without any change in the form of the shingles.

In order to reduce the tendency of the roof to leak by the drivin of rain under the lower edges of the shing es or otherwise I produce on the upper surface of the shingles a depression 25. The edge 19 of the overlying shingle will rest in the depression and rain cannot be driven under the edge 19.

In Figs. 4 to 6 I have illustrated a modif fied type of shingle which is shown with the rows running longitudinally, but which can be inclined if desired. In this type of shingle I provide the tongues 26 and 27 with the slots 28 and 29 and the tongue 26 of the overlying shingle is sli ped through the slit 28 of the adjacent underlying shingle and under the corner 30 thereof; and similarly the tongue 27 is sli of the underlying s ingle and under the corner 31 thereof. So that the opposite sides of the adjacent shingles in the same row are interlocked in somewhat a similar manner as described with reference to the shingles of Fig. 2. In this shingle also a depression 32 is provided to revent any water being driven under the lower edge of the overlying shingle.

Fig. 7 illustrates how the strips of shingles may be shifted in assembling in order to vary the ap earance of the roof. These shingles are 0 the same shape as those of Fig. 4, and are interlocked in a similar manner, but the interlocked strips are shifted so that the respective edges 35 register.

I claim as my invention:

1. A shingle havin a parallelogram, an having tongues projecting outwardly from one edge and adjacent the opposite corners of the edge, said shingle having slits in the two adjacent edges, the slits being adjacent the other two corners of the shingle, and the tongues being adapted to slip into the slits of other similarly formed shingles.

2. A shingle having the general shape of a parallelogram and having tongues and slits formed in the corners of one edge, and having slits adjacent the other two corners of the shingle, the tongues adapted to pass under the corners of other similarly formed shingles with the slits adjacent the tongues interlocking with the respective slits of the other two corners.

3. A plurality of individual shingles assembled, with bothof the adjacent corners of each pair of shingles interlocked, to form strips with the edges of each strip in line, said strips being assepibled with one edge of one strip overlapping one edge of an adjacent strip.

ped through the slot 29' the general shape of.

their adjacent corners interlocking to form' a strip, said shingles being assembled with the one edge of one strip overlapping a material distance on one edge of an adjacent strip, each of the shingles having a depression extending across its upper surface and the lower edge of the overlying shingle being positioned in said depression.

6. A plurality of shingles assembled in strips with straight edges, with both of the corners of each shingle interlocking with the two adjacent corners of the adjacent shingle of the same strip, said strips bein adapted to be assembled .with other sim'i ar strips with one edge of one strip overlapping a material distance on one edge of an adjacent strip.

7. A plurality of shingles with their adjacent corners interlocking to form a strip, and with the adjacent edge of one strip overlapping on the other strip, each of the shingles having a depression extending across its upper surface, and with the lapping edge of the adjacent shingle in the same strip being positioned in said depression.

8. A plurality of shingles, each having the general sha e of a parallelogram, a tongue projecting from each of the opposite corners, of one edge of each of said shingles, and each shingle having a slit adjacent each of the other two corners,'the shingles being assembled in strips with their edges in line and with the tongues of each shingle pro jec-ting through the slits of an adjacent shingle;

In testimony whereof, I hereunto set my hand.
